FIREARM.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed March 16, 1906. Serial No. 306,377.

To all whom it may concern:

Be it known that CHARLES FRANK SAWTELL, a citizen of the United States,residing at Manchester, in the county of Hillsboro and State of NewHampshire, has invented a new and useful Firearm, of which the followingis a specification.

This invention relates more particularly to that class of fire arms inwhich a single trigger is employed for operating a plurality of hammers.

One of the principal objects is to provide novel, efficient andexceedingly simple means for operatively connecting or associating thetrigger with either hammer controlling mechanism, said means beinglocated in convenient relation to permit its ready operation or change.

Another object is to provide a structure that is composed of acomparatively small number of parts and elements, which are not liableto become deranged or injured, certain of said parts or elementsmoreover performing double functions.

The preferred but not the only embodiment of the invention isillustrated in the accompanying drawing, whereinz Figure l is a top planview of a portion of a fire arm lock, showing the improved structureforming a part thereof. Fig. 2 is a bottom plan view of the same. Fig. 3is a side elevation of the same. Fig. 4 is a longi tudinal sectionalview through the structure. Fig. 5 is a cross sectional view on the line5-5 of Fig. 4. Fig. 6 is a detail perspective view of the trigger. Fig.7 is a similar view of the actuating device.

Similar reference numerals designate corresponding parts in all thefigures of the drawing.

A complete lock is not shown, as the structure is clearly applicable tosubstantially any well known type, as will be apparent to those skilledin the art. A trigger plate is employed, and is designated 8. Said plateis provided with suitable upstanding ears 9, to and between which ispivoted a trigger 10, having the usual depending finger piece 11 locatedbelow the plate 8. Said plate 8 is furthermore provided in advance ofthe ears 9 with an upstanding boss or projection 12, on the oppositesides of which are pivoted separate sears 13, constituting parts of theusual hammer-controlling mechanisms. The sears are urged in onedirection by spring arms 14, secured to the front portion of the triggerplate, and their tails are provided with inwardly extending lugs 15.

The trigger 10 is provided between its ends with an upstanding boxingportion 16 extending through an opening 17 in the trigger plate, saidtrigger also having a transversely disposed guide-way in its underportion, which guide-way includes inwardly extending oppositely disposedand spaced flanges 18. A reciprocatory actuating or connecting device ismounted on the trigger, and is slidable transversely thereof. Saidactuating device includes a reciprocatory finger piece 19, slidable inthe guide-way of the trigger and having channels 20 that receive theflanges 18. The lower surface of the finger piece is preferably roundedand roughened, and is located in advance of the finger piece 11 of thetrigger. A stem 21 is carried by the finger piece and projects upwardlythrough the boxing 16. The upper end of said stem is movable topositions beneath the lug 15 of either sear 13 or to a position betweensaid lugs.

A cross bar 22 passes through the upper portion of the stem 21, and isslidable in recesses 23, formed in the opposite side walls of the boxing16 of the trigger. This cross bar is held in place in the stem by a pin24 projecting fromithe stem and operating between the side Walls of theboxing. Notches 25 are formed in the upper side of the cross bar onopposite sides of the stem, and spring arms 26, formed by a double wirebear upon the upper side of the cross bar on opposite sides of theboxing, and are arranged to engage in the notches 25. Thespring extendslongitudinally along the rear portion of the trigger plate and is heldin position by a suitable screw or other fastener 27, the arms beingalso preferably located between stop pins 28 mounted on the plate. I

It is believed that the operation of the structure can now be madeclear. If for instance it is desired to discharge the right hand barrelof the fire arm, it is only necessary for the gunner to push the fingerpiece 19 to the right, whereupon the stem 21 will be brought beneath thelug 15 of theright hand sear 13, which sear controls the right handbarrel as is well understood. Consequently if the trigger 11 is pulled,the stem being raised thereby, will cause the elevation of the rear endof the sear, and the release of the hammer controlled by it. Thismovement of the trigger, however, has no effect on the left hand sear.,The actuating or controlling device is moreover locked in this positionby the spring arms 26 engaging in certain of the notches 25 of the crossbar. To discharge the other barrel, it is only necessary to push thefinger piece in an opposite direction, whereupon the actuating device orstem will be moved out of coaction with the right hand sear, and intocoaction with the left hand sear, said actuating device being alsolocked in this position by the spring arms 26 engaging in the othernotches. By placing the actuating device in a central position, the stemwill be located in a plane between the lugs 15 of the sears, andtherefore an actuation of the trigger will not effect the operation ofeither sear. Consequently a safety device is also provided. It will beapparent that this structure is exceedingly simple, and at the same timeis entirely effective for the desired purposes. The parts or elementsmoreover are of a nature not liable to derangement or to becomeinoperative. Furthermore certain of the parts perform double functions.

For instance, the spring arms 26 not only look the actuating device inits different positions, but bearing down on said actuating device,consequently bear down on the trigger, and thereby constitute yieldingmeans to resist the movement of said trigger, doing away with thenecessity of an additional spring.

From the foregoing, it is thought that the construction, operation, andmany advantages of the herein described invention Will be apparent tothose skilled in the art, Without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what- I claim as new, anddesire to secure by Letters Patent, is:

1. In a fire arm, the combination with a plurality of hammer controllingmechanisms,-of a trigger, and a re clprocatory actuating device slidablymounted on the underside of the trigger and having a portion movabletransversely thereof into and out of coaction with either hammercontrolling mechanism.

2. In a fire arm, the combination with a plurality of hammer controllingmechanisms, of a trigger, and a reciprocatol'y actuating devicecomprising a finger piece having a slidable interlocking engagement withthe under side of the trigger, and a stem carried by the finger piece,said stem projecting upwardly through the trigger and being movable intoand out of coaction with either hammer controlling mechanism,

3. In a fire arm, the combination with a plurality of hammer controllingmechanisms, of a trigger plate, a
